ビル内の電気設備によって生じる誘導雑音の位置検出方法の研究

本研究的目的是估计噪声产生的位置以及产生噪声的原因。在这两年中，我们主要研究了以下三个主题。(1)为了了解噪声源的特性，我们研究了带有辉光开关的荧光灯和带有触摸传感器的灯的噪声产生机理。(2)为了了解感应噪声在通信电缆上的传播特性，研究了平衡电缆对地不平衡特性，提出了一种新的计算方法。（3）为了抑制噪声，采用了共模扼流圈。提出了一种共模扼流圈的等效电路，用于分析含共模扼流圈的电缆电路。

The object of this research is to estimate a position where noise has been generated and from what it has been generated. In these two years, we have mainly researched about next three subjects. (1) To know characteristics of noise source, we investigated a generation mechanism about noises from a fluorescent light with glow switch and a lamp with touch sensor. (2) To know propagation characteristics of induced noise on communication cable, we investigated characteristics of unbalance about earth of the balanced cable and proposed a new calculation method of it. (3) For noise suppression, a common mode choke is used. We proposed an equivalent circuit of common mode choke to analyze a cable circuit including a common mode choke.
